LAMP non AUTOMOBILES, &c.

Specificaticin of Letters Patent.

Patented Jan. 19, 1909 Application filed Kay 23, 1908. Serial No. 434,470.

To all whom it may concern:

Be it known that I, CLARENCE I-I. BRYAN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lamps for Automobiles, &c., of which the following is a full, clear, and exact specification.

My invention is concerned with a novel lamp designed especially for use in automobiles, but which may be adapted for use elsewhere. I

It consists essentially in alamp provided with two burners in proximity to each other, one of which is associated with an oil receptacle and adjustable wick furnishing a relatively feeble and cheap illuminant, and the other with a powerful andmore expensive illliminant, such as acetylene gas, which is adapted to be turned on or ofi, as needed, from the seat of an automobile, while the other is allowed to burn constantly while the lamp is in use, acting, as it were, as a pilot light for the main or acetylene burner.

To illustrate my invention, I annex hereto.

a sheet of drawings, in which the same reference characters are used. to designate identical parts in all the figures, of which,

, Figure 1 is a side elevation of a portion of an automobile equipped with a lamp embodying my invention; and Fig. 2 is a side elevation of the lamp. proper, with a portion of the casing broken away and the acetylene burner in section. ,1

In carrying out my invent-ion, a casing a of any ordinary construction may be em-' ployed, and in its embodiment I employ an oil receptacle 6, which has the burner c in the casing in proper location relative to the reflector d and the bulls eye 6 which is customarily employed with automobile and similar lamps. Immediately adjacent the burner c and in close proximity to the reflector d, I locate a second burner f, which is preferably a'burner for acetylene gas, or some other gaseous illuminant which is capable of producing a powerful flame, and connected with this burner f is the stem 9 extending through the rear of the lamp and provided with the nipple II;- by which it is 'front of the hood and at such a distance from the drivers seat that he cannot manipulate the oil burner without leaving his seat. The operation of my improved device will bereadily apparent: When starting on a trip at night, the oil burner c is ignited and set for as feeble an illumination as may be desired, it being understood, .of course, that any oil flame is relatively feeble in comparison with the acetylene flame. The driver from his seat can then turn the valve m to throw the generatorinto operation and allow the gas to flow to the burner f, where it is ignited from the=oil flame, and furnishes a powerful illumination when needed. If it is desired to cut ofl the powerful illumination, it can be effected from the drivers seat by closing the valve m, and when it is to be thrown on again, it is only necessary to turn the valve, the gas, of course, being ignited from the flame of the burner c. If

the generator should fail temporarily in its operation, as sometimes happens, when the.

gas begins to flow again it Will at once be ignited, thus presenting a marked improvement over the ordinary acetylene lamp unprovided with the auxiliary burner. The utility of such a lamp will be readily apparent, as when driving through the well lighted streets of a city, or in the open on a moonlight night, the gas may be turned oif, leaving only the lesser illumination necessary to comply with the laws regulating their use. When ill lighted streets, or a stretch of forest road, are reached, the acetylene cock is turned on by the driver from his seat, and the gas is instantly ignited from the oil flame, thus furnishing a powerful illumination instantly, when it is needed, and only for so long as it is needed, as the. driver can turn it off without leaving his seat or stopping the car. In case the illuminant for either burner becomes exhausted, the supply of the other, being independent, will still be available.

I-Vhile I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of some modification, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.

hat I claim as new, and desire to secure by Letters Patent of the United States, is:

1. a carriage lamp, the combination with a lamp casing, of an illuminating oil burner therein, means for adjusting a wick in said burner, and an oil receptacle associated therewith into which the wick extends, the oil being adapted to burn constantly as an illuminating and pilot light, a gas burner in said casing adjacent to the oil burner so that gas starting to flow therefrom will be ignited by the pilot flame, and means for supplying gas to the burner and controlling said supply from a distance. 7

2. In a carriage lamp, the combination with alamp casing, of an illuminating oil burner therein, means for adjusting a wick in said burner, and an oil receptacle associated therewith into which the wick extends, the oil being adapted to burn constantly as an illuminating and pilot light, an acetylene gas burnerlocated in said casing adjacent to the oil burner so that gas starting to flow.

therefrom will be ignited by the pilot flame,

F a generator at a distance from the burner,

connections between said generator and gas burner, and a cock for controlling the gas supply at a distance from the lamp.

3. In a carriage lamp, the combination] wlth a lamp casing havlng a smoke flue at burn constantly as'an illuminatmg and pilot light, a gas burner in said casing also' between the lens and the reflector and adjacent to the oil burner so that as starting to flow therefrom will be ignited-by the pilot flame, and means for supplying as to the .burner and controlling said supp y from a distance.

In witness whereof, I have hereunto set my hand and aflixed my seal, this 21st day of May, A D. 1908. i
